Abstract

The method involves providing disengaged and fixed toothed belts (3, 4) including a succession of teeth, on surfaces of a rolled and unrolled shutter (2), where the belts are placed opposite to one another, and the belt (3) is placed opposite to a non-toothed belt. A position of the teeth of the belts is adapted by deformation of the belts, for permitting the belts from being engaged from one another. The position of the teeth of the belts is stabilized with respect to the shutter.

Description

La présente invention est relative à un procédé de fabrication d'un volet destiné à être enroulé et déroulé présentant sur chacune de ses faces une courroie, ces deux courroies étant situées en regard l'une de l'autre et coopérant l'une avec l'autre d'une manière telle qu'une de ces courroies puisse entraîner l'autre courroie. Il s'agit de préférence de deux courroies crantées.The present invention relates to a method of manufacturing a flap intended to be wound and unrolled having on each of its faces a belt, these two belts being located facing one another and cooperating with each other. other in such a way that one of these belts can drive the other belt. It is preferably two toothed belts.

Un problème important de ce type de volet à courroies crantées résulte du fait que, lors de son enroulement, la distance entre deux dents consécutives change constamment. En effet, cette distance dépend non seulement de l'angle de courbure du volet enroulé, mais varie également d'une manière continue au fur et à mesure de cet enroulement. De plus, pour des volets et des courroies dont l'épaisseur peut varier, il faut également tenir compte de cette variation aux endroits où les courroies sont fixées sur le volet. Ainsi, pour permettre que la courroie située sur une des faces puisse s'engrener avec la courroie sur l'autre face, il faut que la distance entre deux dents consécutives d'une des courroies soit adaptée à celle entre les dents de l'autre courroie en absorbant toutes les tolérances en épaisseur et en longueur.An important problem of this type of toothed belt flap results from the fact that, during its winding, the distance between two consecutive teeth changes constantly. Indeed, this distance depends not only on the angle of curvature of the wound flap, but also varies continuously as this winding. In addition, for flaps and belts whose thickness may vary, it is also necessary to take into account this variation where the straps are fixed to the flap. Thus, to allow the belt on one side can mesh with the belt on the other side, it is necessary that the distance between two consecutive teeth of one of the belts is adapted to that between the teeth of the other belt absorbing all tolerances in thickness and length.

Il a été constaté que, sur base des connaissances actuelles de l'homme du métier, ceci n'est pas réalisable avec la précision requise pour obtenir un engrènement parfait de deux courroies coopérant l'une avec l'autre.It has been found that, on the basis of the current knowledge of those skilled in the art, this is not possible with the precision required to obtain perfect meshing of two belts cooperating with each other.

Un des buts essentiels de la présente invention est de proposer une solution extrêmement simple et très efficace à ce problème, qui ne nécessite aucune connaissance technique particulière et qui peut être obtenue en un minimum de temps.One of the essential aims of the present invention is to propose an extremely simple and highly effective solution to this problem, which does not require any particular technical knowledge and which can be obtained in a minimum of time.

A cet effet, dans le procédé suivant l'invention, l'on adapte la position des dents d'au moins une des courroies, lors de l'enroulement du volet simultanément avec les courroies, par la déformation de cette courroie d'une manière telle à permettre aux deux courroies de s'engrener et l'on stabilise ensuite cette position des courroies par rapport au volet.For this purpose, in the method according to the invention, the position of the teeth of at least one of the belts, during the winding of the shutter simultaneously with the belts, is adapted by the deformation of this belt in a manner such as to allow the two belts to mesh and then stabilize this position of the belts relative to the flap.

Suivant une première forme de réalisation particulière de l'invention, l'on enroule le volet pendant que l'on fait engrener une courroie libre par rapport au volet et placée en regard d'une des faces de ce dernier avec une courroie préalablement fixée sur la face opposée du volet, cet engrènement ayant lieu au fur et à mesure de l'enroulement du volet au moment où ces deux courroies viennent en contact l'une avec l'autre, la courroie libre étant ensuite fixée au volet à la face opposée à celle de la courroie fixe pendant que les dents des courroies se sont engrenées.According to a first particular embodiment of the invention, the shutter is wound while a free belt is engaged with respect to the shutter and placed facing one of the faces of the latter with a belt previously fixed on the opposite side of the shutter, this meshing occurring as and when the winding of the flap at the moment when these two belts come into contact with each other, the free belt then being fixed to the flap at the opposite side to that of the fixed belt while the teeth of the belts have intermeshed.

Suivant une deuxième forme de réalisation particulière de l'invention, l'on fait engrener les deux courroies l'une avec l'autre, avant qu'elles soient fixées au volet et l'on enroule ensuite le volet simultanément avec les deux courroies de manière à ce qu'elles soient insérées entre les spires successives du volet enroulé et, par conséquent, entre les faces opposées du volet, chacune des courroies étant alors fixée à la face en regard du volet pendant l'enroulement de ce dernier.According to a second particular embodiment of the invention, the two belts are meshed with each other before they are fixed to the flap and the flap is then wound simultaneously with the two belts of the invention. so that they are inserted between the successive turns of the wound flap and, therefore, between the opposite faces of the flap, each of the belts then being fixed to the opposite face of the flap during the winding of the latter.

Suivant une troisième forme de réalisation particulière, l'on place une courroie en une matière plastique, en particulier thermoplastique ou thermodurcissable, sur une des faces du volet, et l'on prévoit en regard de cette courroie sur l'autre face du volet une courroie crantée, le volet étant ensuite enroulé de sorte que, lors de cet enroulement, les dents de la courroie crantée pénètrent dans la courroie en la matière plastique en formant des dents dans cette dernière de manière à faire engrener ainsi les courroies l'une dans l'autre. Ensuite, on fait durcir la matière plastique pour stabiliser la position des dents par rapport au volet.According to a third particular embodiment, a belt made of a plastic material, in particular thermoplastic or thermosetting, is placed on one of the faces of the shutter, and it is provided with regard to this belt on the other face of the shutter a toothed belt, the flap then being wound so that, during this winding, the teeth of the toothed belt penetrate into the belt of the plastic material by forming teeth in the latter so as to mesh the belts and one in the other. Then, the plastic is cured to stabilize the position of the teeth relative to the flap.

D'une façon générale, la présente invention concerne un procédé de fabrication d'un volet destiné, en particulier, à la fermeture d'une baie ou autre ouverture, telle qu'une fenêtre, du volume de chargement d'un véhicule, tel que d'un camion, d'un bateau ou d'un caisson, au recouvrement d'une piscine, etc.In general, the present invention relates to a method of manufacturing a flap intended, in particular, for closing a bay or other opening, such as a window, of the loading volume of a vehicle, such as than a truck, a boat or a box, covering a swimming pool, etc.

Il s'agit notamment d'un procédé de fabrication d'un volet destiné à être enroulé et déroulé entre une position d'ouverture et une position de fermeture. A cet égard, deux courroies crantées sont prévues de préférence à proximité des bords latéraux du volet, en regard l'une de l'autre pour que, lors de l'enroulement et le déroulement du volet, les deux courroies s'engrènent l'une dans l'autre.It is in particular a method of manufacturing a flap intended to be wound and unrolled between an open position and a closed position. In this respect, two toothed belts are preferably provided near the lateral edges of the flap, facing one another so that, during the winding and unwinding of the flap, the two belts mesh with each other. one in the other.

Suivant l'invention, l'on adapte la position des dents d'au moins une des courroies, lors de l'enroulement du volet, en déformant cette courroie, de préférence suivant sa direction longitudinale, d'une manière telle à permettre aux deux courroies de s'engrener et l'on stabilise cette position des courroies par rapport au volet pour maintenir ladite courroie dans la position déformée.According to the invention, the position of the teeth of at least one of the belts is adapted, during the winding of the flap, by deforming this belt, preferably in its longitudinal direction, in such a way as to allow the two The belts engage and stabilize this position of the belts with respect to the flap to maintain said belt in the deformed position.

Suivant la première forme de réalisation représentée à la figure 1, l'on enroule un volet 2 autour d'un tambour 1 pendant que l'on fait engrener une courroie 3, qui n'est pas fixée sur le volet 2 et qui est placée en regard d'une des faces de ce dernier, avec une courroie 4 fixée sur sa face opposée à celle orientée vers le tambour 1, cet engrènement étant alors réalisé au fur et à mesure de l'enroulement du volet 2.According to the first embodiment shown in figure 1 a flap 2 is wound around a drum 1 while a belt 3 is engaged which is not fixed on the shutter 2 and which is placed facing one of the faces of the latter, with a belt 4 fixed on its opposite side to that facing the drum 1, this meshing then being achieved as the winding of the flap 2 is wound up.

Afin de faire engrener les dents des courroies, l'on soumet la courroie libre 3 à une traction dans sa direction longitudinale, comme indiqué par la flèche 5, dans le sens opposé au sens d'enroulement du volet 2, indiqué par les flèches 6.In order to mesh the teeth of the belts, the free belt 3 is subjected to traction in its longitudinal direction, as indicated by the arrow 5, in the direction opposite to the winding direction of the shutter 2, indicated by the arrows 6 .

Cette traction a lieu au fur et à mesure de l'enroulement du volet 2 d'une manière telle à ce que celle-ci soit allongée en fonction de la position des dents de la courroie fixe 4 et que les deux courroies 3 et 4 puissent s'engrener l'une dans l'autre lorsqu'elles sont appliquées l'une contre l'autre.This traction takes place as and when the winding of the flap 2 in such a way that it is lengthened according to the position of the teeth of the fixed belt 4 and that the two belts 3 and 4 can mesh with each other when they are applied against each other.

A cet égard, il est important qu'au moins la courroie libre 3 ne soit pas seulement flexible mais puisse être quelque peu allongée sous l'effet de la traction précitée. Pour cette raison, au moins la courroie 3 est réalisée en un caoutchouc ou une matière analogue relativement dure, mais légèrement extensible et de préférence quelque peu élastique. Avantageusement, les deux courroies 3 et 4 sont réalisées en la même matière.In this regard, it is important that at least the free belt 3 is not only flexible but may be somewhat elongated under the effect of the aforementioned traction. For this reason, at least the belt 3 is made of a rubber or a a relatively hard, but slightly extensible, and preferably somewhat elastic, analogous material. Advantageously, the two belts 3 and 4 are made of the same material.

Lors de l'engrènement, la courroie libre 3 est fixée à la face du volet opposée à celle avec la courroie 4. La fixation de la courroie 3 sur le volet 2 a lieu avec un adhésif fluide 7 qui est injecté entre le volet 2 et la courroie 3, juste avant que le volet 2 entre en contact avec la courroie 3. Cet adhésif 7, qui est alors comprimé entre le volet 2 et la courroie 3, peut durcir lors de l'enroulement pour former un lien solide.During meshing, the free belt 3 is fixed to the face of the shutter opposite to that with the belt 4. The fastening of the belt 3 on the shutter 2 takes place with a fluid adhesive 7 which is injected between the shutter 2 and the belt 3, just before the flap 2 comes into contact with the belt 3. This adhesive 7, which is then compressed between the flap 2 and the belt 3, can harden during winding to form a solid bond.

Comme variante, on peut utiliser, au lieu d'un adhésif fluide, une bande à deux faces collantes. Cette variante peut être considérée comme un équivalent technique. Une telle bande, lorsqu'elle est suffisamment résistante peut former un renforcement de la courroie en cause. Cette forme de réalisation n'a pas été représentée aux figures.Alternatively, instead of a fluid adhesive, a two-sided adhesive tape may be used. This variant can be considered as a technical equivalent. Such a band, when sufficiently strong, may form a reinforcement of the belt in question. This embodiment has not been shown in the figures.

Dans une autre variante, la fixation de la courroie 3 sur le volet 2 peut être réalisée par soudage, brasage ou tout technique équivalente.In another variant, the attachment of the belt 3 to the flap 2 may be performed by welding, brazing or any equivalent technique.

Dans la forme de réalisation représentée à la figure 1, le pas entre deux dents de la courroie 3 avant l'allongement de cette courroie 3 peut être quelque peu plus grand que le pas entre les dents de la courroie 4. Ainsi, la force de traction à exercer sur la courroie 3 peut être moindre que lorsque les pas des deux courroies 3 et 4 sont identiques. La différence entre les pas des dents de ces courroies 3 et 4 est dépendant du diamètre des spires formant le rouleau du volet 2, en particulier de la courbure de ces spires, et est, par exemple, de l'ordre de 8%.In the embodiment shown in figure 1 , the pitch between two teeth of the belt 3 before the elongation of this belt 3 may be somewhat larger than the pitch between the teeth of the belt 4. Thus, the traction force to be exerted on the belt 3 may be less only when the steps of the two belts 3 and 4 are identical. The difference between the pitch of the teeth of these belts 3 and 4 is dependent on the diameter of the turns forming the roller of the shutter 2, in particular of the curvature of these turns, and is, for example, of the order of 8%.

Suivant la deuxième forme de réalisation représentée à la figure 2, l'on fait engrener deux courroies 3 et 4 l'une avec l'autre avant de les fixer au volet 2. Le pas des dents des courroies 3 et 4, lorsqu'ils sont à plat, est généralement sensiblement identique.According to the second embodiment shown in figure 2 two belts 3 and 4 are meshed with each other before being fixed to the flap 2. The pitch of the teeth of the belts 3 and 4, when they are flat, is generally substantially identical.

Ensuite, l'on enroule le volet 2 simultanément avec les deux courroies engrenées 3, 4 de sorte qu'elles soient insérées entre les spires successives du volet enroulé et, par conséquent, entre les faces opposées de ce dernier. Par cet enroulement, au moins une des courroies est déformée quelque peu dans sa direction longitudinale.Then, the shutter 2 is wound simultaneously with the two intermeshing belts 3, 4 so that they are inserted between the successive turns of the wound flap and, consequently, between the opposite faces of the latter. By this winding, at least one of the belts is deformed somewhat in its longitudinal direction.

On fixe les deux courroies 3 et 4 à la face en regard du volet 2 pendant l'enroulement de ce dernier, de la même manière que la courroie 3 de la première forme de réalisation.The two belts 3 and 4 are fixed to the opposite face of the shutter 2 during the winding thereof, in the same way as the belt 3 of the first embodiment.

La troisième forme de réalisation, telle que représentée à la figure 3, se distingue essentiellement par rapport aux deux formes de réalisation précédentes par le fait qu'au départ on fait usage d'une courroie non-crantée 4', formée d'une simple bande en une matière thermoplastique ou thermodurcissable connue en soi, que l'on fixe sur la face du volet 2 opposée à celle orientée vers le tambour 1. Dans cette forme de réalisation, aucune traction n'est exercée sur la courroie 4'.The third embodiment, as shown in FIG. figure 3 , differs essentially in relation to the two previous embodiments in that at the beginning is used a non-toothed belt 4 ', formed of a single strip of a thermoplastic or thermosetting material known per se, that the it is fixed on the face of the flap 2 opposite to that facing the drum 1. In this embodiment, no traction is exerted on the belt 4 '.

En regard de la courroie 4', sur l'autre face du volet 2, on prévoit une courroie crantée 3 qui peut être fixée au volet de la même façon que dans les deux formes de réalisation précédentes.Next to the belt 4 ', on the other face of the flap 2, there is provided a toothed belt 3 which can be fixed to the flap in the same way as in the two previous embodiments.

Lors de l'enroulement du volet 2, les dents de la courroie crantée 3 pénètrent dans la courroie 4' en matière plastique de manière à transformer la courroie 4' en une courroie crantée 4 qui engrène avec la courroie 3.During the winding of the flap 2, the teeth of the toothed belt 3 penetrate into the plastic belt 4 'so as to transform the belt 4' into a toothed belt 4 which meshes with the belt 3.

Ensuite, on fait durcir la matière plastique, d'une manière connue en soi, pour stabiliser la position des dents des courroies 3 et 4 ainsi engrenées. A cet égard, la matière plastique contient éventuellement un durcisseur également connu en soi.Then, the plastic is cured, in a manner known per se, to stabilize the position of the teeth of the belts 3 and 4 thus meshed. In this respect, the plastic material optionally contains a hardener also known per se.

La figure 4 représente un tambour 1 qui présente une section perpendiculaire à son axe de rotation ayant sensiblement l'allure d'une spirale. La paroi 1' du tambour représenté à la figure 4 est pourvue à ses bords latéraux d'une succession d'encoches 8 dans lesquelles peuvent pénétrer les dents d'une courroie crantée 3. Ces encoches 8 ont par exemple une forme correspondant à celle de la courroie crantée 3.The figure 4 represents a drum 1 which has a section perpendicular to its axis of rotation having substantially the shape of a spiral. The wall 1 'of the drum shown in FIG. figure 4 is provided at its lateral edges with a succession of notches 8 into which the teeth of a toothed belt 3 can penetrate. These notches 8 have for example a shape corresponding to that of the toothed belt 3.

La figure 5 représenté un détail de deux courroies crantées 3 et 4 fixées, lors de l'enroulement du volet 2, directement sur chacune des faces d'un volet 2, comme c'est le cas dans les formes de réalisation des figures 1 à 3.The figure 5 shown a detail of two toothed belts 3 and 4 fixed, during the winding of the shutter 2, directly on each of the faces of a shutter 2, as is the case in the embodiments of the Figures 1 to 3 .

La figure 6 concerne une forme de réalisation qui se distingue de celle représentée à la figure 5 par le fait que le bord latéral du volet 2 est formé par une bande flexible 9 contenant une armature de renforcement 10 s'étendant dans la direction longitudinale de cette bande 9. Dans cette forme de réalisation, les courroies crantées 3 et 4 sont fixées sur la bande 9 par collage ou soudage ou tout autre moyen équivalent.The figure 6 an embodiment which differs from that shown in FIG. figure 5 in that the lateral edge of the flap 2 is formed by a flexible band 9 containing a reinforcing reinforcement 10 extending in the longitudinal direction of this band 9. In this embodiment, the toothed belts 3 and 4 are fixed on the band 9 by gluing or welding or any other equivalent means.

L'armature 10 n'est, toutefois, pas toujours indispensable, p.e. dans le cas où la bande elle-même est suffisante résistante.The armature 10 is, however, not always essential, eg in the case where the band itself is sufficiently resistant.

La forme de réalisation représenté à la figure 7 se distingue par rapport à celle de la figure 6 par le fait qu'une des courroies crantées 3 forme un tout avec la bande 9, c.-à-d. est constituée d'une seule pièce avec cette dernière.The embodiment shown at figure 7 differs from that of the figure 6 in that one of the toothed belts 3 forms a whole with the band 9, i.e. consists of a single piece with the latter.

Dans les deux formes de réalisation représentées aux figures 6 et 7, les courroies crantées 3 et 4 sont fixées au bord latéral du volet 2 formé par la bande 9.In both embodiments represented at Figures 6 and 7 , the toothed belts 3 and 4 are fixed to the lateral edge of the shutter 2 formed by the band 9.

Suivant une variante du procédé suivant l'invention, la bande 9 avec les courroies 3 et 4, fixées de part et d'autre de cette dernière, est enroulée indépendamment du corps du volet 2, c.à.d. avant de la fixer à ce dernier. Par « corps du volet », il ya donc lieu d'entendre la partie du volet 2 sans la bande 9.According to a variant of the method according to the invention, the band 9 with the belts 3 and 4, fixed on either side of the latter, is wound independently of the body of the flap 2, ie. before fixing it to the latter. "Shutter body" means the part of shutter 2 without band 9.

Les courroies crantées 3 et 4 sont de préférence constituées d'un élastomère, comme du polyuréthanne, de sorte que ceux-ci peuvent être fixées sur le volet 2 même ou sur ladite bande flexible 9 de ce dernier par collage ou par soudage.The toothed belts 3 and 4 are preferably made of an elastomer, such as polyurethane, so that they can be fixed on the flap 2 itself or on said flexible strip 9 of the latter by gluing or welding.

Il est bien entendu que l'invention n'est pas limitée aux différentes formes de réalisation décrites ci-dessus et illustrées par les figures annexées, mais que d'autres variantes encore peuvent être envisagées sans sortir du cadre de la présente invention.It is understood that the invention is not limited to the various embodiments described above and illustrated by the accompanying figures, but that other variants can be envisaged without departing from the scope of the present invention.

Les dents pourraient, en effet, avoir des formes très variées pour autant que les dents d'une des courroies puissent pénétrer dans les entailles entre les dents de l'autre courroie et prendre appui sur ces dernières lors du déroulement du volet.The teeth could, in fact, have very varied forms as long as the teeth of one of the belts can penetrate into the notches between the teeth of the other belt and bear on these during the unwinding of the flap.

C'est ainsi que, dans certains cas, les dents peuvent être formées par des tétons répartis uniformément sur une des courroies et des entailles formées par des creux correspondants dans l'autre courroie.Thus, in some cases, the teeth may be formed by pins uniformly distributed on one of the belts and notches formed by corresponding recesses in the other belt.

De plus, il n'est pas absolument nécessaire qu'un jeu existe entre les dents des deux courroies engrenées.In addition, it is not absolutely necessary that a game exists between the teeth of the two meshed belts.
